Subject: [PATCH] drm/panel-edp: Add LGD LP129WT112684 panel
Date: Thu, 12 Nov 2026 10:44:44 -0500 [thread overview]
Message-ID: <20261112154444.417-1-_@tawheed.cc> (raw)
Add the LG Display LP129WT112684 12.9" 2880x1920 eDP panel, used in the
Microsoft Surface Pro X (SQ1). It uses the same timings as the other
LGD LP129WT* panel already in the table (0x06b2).
Without this entry the panel is driven with conservative timings and
probe hits the "Unknown panel" WARN.
Panel ID: LGD 0x0555, EDID descriptors "LGD_DV1.0_" / "LP129WT112684".
